Abstract: Drilling for laboratory testing of concrete and foundation rock was carried out for the U. S. Army Engineer District, Chicago, as part of a major rehabilitation program at the Starved Rock Lock and Dam. The structures are on the Illinois Waterway. This report covers the work accomplished during the Phase II program entitled "Compliance and Scour Detection."

Summary: A two-dimensional finite element seepage computer program for solving complicated seepage problems has been developed.

Summary: This report is a review of the materials, specifications, procedures, equipment, and testing pertinent to construction and compaction control of the earth-fill embankment of Littleville Dam, Westfield River, Mass., constructed by the U. S. Army Engineer Division, New England.

Introduction: The purpose of this study was to assess the capabilities of the WES geophysical downhole logging equipment for obtaining in situ bulk densities and water contents in unconsolidated materials, to establish a log analysis procedure applicable from one site to another, and to compare geophysically derived properties with those obtained from laboratory analysis of samples.

Abstract: This report presents and summarizes guidance for design of bottom longitudinal filling and emptying systems for navigation locks.

Abstract: Field tests were conducted at several sites in Louisiana to determine the effectiveness of two geophysical tools for detecting and locating subsurface geological features in alluvial terrain.

Abstract: This paper describes a general concept that will serve as a basis for developing well-conceived aquatic plant management plans, as well as a step-by-step guide for implementing measures for long-term aquatic plant control while giving proper consideration to their potential long-term effects on the environment.

Summary: Several series of laser instrument alignment surveys were made at the exterior roadway deck level and within the interior inspection gallery of Keystone Dam, Oklahoma, and compared with theodolite surveys over the same lines and under similar conditions.

Summary: This report is a review of the materials, specifications, procedures, equipment, and testing pertinent to construction and compaction control of the earth-fill embankment of Littleville Dam, Westfield River, Mass., constructed by the U. S. Army Engineer Division, New England.

Abstract: A crack survey , drilling, field and laboratory testing of concrete, and laboratory testing of foundation rock were carried out as part of a major rehabilitation and compliance program at Lockport Lock.

Abstract: A brief review of the engineering nature of water utilities is presented along with simplified techniques for estimating the cost of various types of water utility projects.

Abstract: Drilling for laboratory testing of concrete and foundation rock was carried out for the U. S. Army Engineer District, Chicago, as part of a major rehabilitation program at the Starved Rock Lock and Dam.

Abstract: Physical property data of concrete and foundation rock for use in a stability analysis and the design of an anchorage system of grouted tendons are presented in this report.

From summary: Site investigations were conducted at two locations, the sites of the DUGOUT and CHARLIE events, at the Nevada Test Site for the purpose of evaluating the dynamic in situ technique as a means of determining the boundaries of craters produced by explosive detonations.
